Answer 1

Step 1: You will need to find the radius using the formula: C = 2πr
518.1 = 2πr
r = 518.1 / (2*π)
r ≈ 82.4 feet

Step 2: You will need to substitute your answer into the formula for a cylinder.
V = πr^2h
V = π(82.4)^2(82.4)
V ≈ π(6777.76)(82.4)
V ≈ 175,849.18 cubic feet

Step 3: The approximate volume of Spaceship Earth is 175,849.18 cubic feet. The unit we would use is cubic feet.
